  1. Liver Disease in Canada: A Crisis in the Making An Assessment of Liver Disease in Canada Summary of a report prepared by the Canadian Liver Foundation, March 2013

  2. Hepatitis B Hepatitis B 2

  3. Incidence of acute hepatitis B is declining Acute hepatitis B infection rate over time Indeterminate cases are cases in which neither acute hepatitis B nor chronic hepatitis B could be determined with certainty. This may have been due to confusing serological tests or to inadequate follow-up. http://www.phac-aspc.gc.ca/id-mi/hepatitisBCan-hepatiteBCan-eng.php

  4. Vaccinated age groups show the greatest decline in acute hepatitis B Acute hepatitis B infection rate by time and by age group Indeterminate cases are cases in which neither acute hepatitis B nor chronic hepatitis B could be determined with certainty. This may have been due to confusing serological tests or to inadequate follow-up. http://www.phac-aspc.gc.ca/id-mi/hepatitisBCan-hepatiteBCan-eng.php

  11. Reimbursement policies for hepatitis B drugs No recommendation: (licensed before CDEC was established) Restricted to internal medicine specialists and designated prescribers (except standard IFN, not listed) Usual clinical restrictions only Usual clinical restrictions only Sources = CADTH, provincial formularies, Kelly Kaita (personal communication) CDEC = Canadian Drug Expert Committee *Ontario and other provinces allow entecavir to be used for LAM resistance despite all practice guidelines suggesting that entecavir is not appropriate for LAM resistance **Only 96 cases of hepatitis B reported in PEI. Treatment status not known

  12. Hepatitis B vaccination policies by province The recommended vaccination schedule is neonatal vaccination at birth, 4 weeks and 6 months of age.
